SPECIFICATION forrning part of Letters Patent No. 500,794, dated July 4,1893. Application filed January 12, 1892i. Serial No. 458,133. (Nomodel.)

To all whom it may concern.l

Be it known that I, GEORGE W. M. BOWEN,

` a citizen of the United States, residing at Glem coe, in the county ofDodge and State ot' Nebraska,have invented a new and useful Journal-BOX,of whichthe following is a specification.

My invention relates to improvements in journal-boxes; the objects inview being to provide a box adapted by its peculiar con-` struction toreduceV friction in bearings of Journals; and to so construct andarrange the box aste adapt the same to be adjusted for the purpose ofcompensating for wear.

lVith these various objects in View the i.n vention consists in certainfeatures of construction hereinafter specified and particu larly pointedont in the-claims.

Referring to the drawingsz-Figure 1 is a vertical longitudinal sectionof a j ournal-.box constructed in accordance with my invention. Fig. 2is a transverse sectional view. Fig. 3 is an end elevation upon anenlarged scale with the end-cap removed. Fig. 4. is a detail of thecentral or main roller for receiving the shaft or axle. Fig. 5 is asimilar view of one of the auxiliaryrevolvers or rollers.

Like numerals of reference indicate like parts in all'theffigures ofthedrawings.

In practicing .my invention I employ two conical shells 1,1whose basesare opposed to each other. The inner ends of the said shells areprovided with longitudinally-disposed a'nnular ilanges 2, the flange ofone shell being slightly greaterin diameter than, and adapted to receivethat of the other shell, whereby it may be said they in any mannertelescope to a limited degree. At the juncture between the flanges 2 andthe shells the said shells have theirbases provided withr radial flanges3 which oppose each otherand'are perforated at intervals, as at 4:, forthe reception of bolts 5, which serve to clamp the shells together andadjust the same for purposes hereinafter apparent by means of theirnut-s6. The outer or frustum-like ends of the shells are provid ed withexternal L-shaped flanges 7 whose edges are provided with a series ofteeth 8, the same being longitudinally-disposed.

extending the entire length of the flange and y The external surfaces ofthese flanges have fitted thereover less diameter at its center.

end-caps 9 by which dust is excluded from the bearings. l

Located centrally in theshells 1 and extending from end to end thereof,is the main roller 10 whose 'periphery or surface is reduced graduallytoward its center so that it Vresembles two frustums of cones, whoseapices or frustum ends are joined. This. forms a convex surface 11,which as will be seen, isof The outer ends or bases of the roller areslightly reduced and provided with a series of teeth 12. l The' roller10 is bored internally as at 13, and is designed to receive and havesecured therein by any ordinary means, as a key for instance, the shaftAs before stated, this roller 10 is located within the conical shells 1.Surrounding the roller 10 and' located at intervals, for instance one-`eighth of an inch apart, is' a series of auxiliaryrollers l5, which incontradistinction tothe roller 10 has its external surface reduced fromitscenter or points at each side of the same toward its ends, so that itresembles in external appearance a pair ot' cones having their basesjoined. In this mannerit will be seen that the reduced surfaces 1G areformed at each side of the center of the roller. Each of the rollers 15is further provided with a central annular depression or groove 17 andthe ends of the rollers are provided with spurgears 18. The rollers 10and 15 are so proportioned with relation to the external shells 1 thatthey completely lill the same, that is tocorresponding faces of theshells and the mailtrollerlO. At the same tilnethespilr-.gears 1S willengage the spur-gears l2 of the main roller and will also engage theteeth 8 at the ends of the shells, which latter teetlrare wider thanthose of the gears 1S and about correspond' with those of the roller 10.It will be seen that the teeth S and 12 serve to maintain the rollers 15in proper relative position and prevent theni from coming together. Atthe same time it will be observed that the internal roller 10 may freelyrevolve, the friction being reduced to a minimum by the employ.- ment ofthe auxiliary rollers 1,5.. -As wear oecurs it is simply necessary toadjust the 4nuts `0r axle 14 which it is designed to support.

IOO

6 upon the bolts 5 and thus draw the two conical shells 1 together.AThis of course draws the teeth S inward and it is therefore necessary tohave these teeth 8 slightly wider than t 5 those'ot' the spur-gears 18,and for a similar reason it is necessary that the gears 12 of the., mainroller should be slightly wider than said' spur gearsu 18A. i Q

From the foregoing descriptionin connec, tio'n with the accompanyingdrawings it willv be seen, that I have provided a .journal-box?embodying all of the advantages character-f istic of that class of boxesemploying a seriest otl rollers and commonly called roller-bear ings. Atthe same time I'obviate in such 'a construction the possibility-of theauxiliary rollers working together or' toward each other 'catedbetweenthe main roller and shells and having external coniigurationscorresponding and maintain them strictly'in their proper positions; andfurthermore I provide for a perfect adjustment for compensating for allwear; and finally to secure the advantages overthe ordinaryroller-bearings of the conical roller-bearings, or what is commonly.called a cone-bearing.

Having described myv invention, what I claim is# 1. In a journal-box,the combination with the opposite opposing conical telescoping shellshaving their bases tclcscopically con- 3o nccted and providcd'at oneside thereof with 'annular flanges having porforations, andadjusting-boltslocated thereixnoffa'central main rollerbored toreceivelan :axle and' having an Iexternal conguration opposite to thatof the shells, and a series of auxiliary rollers located v between themain roller and shell and having al1-external configuration opposite tothat of the shell and mainroller, substantially as specified.

.2. In a journal-box, the combination with 4o opposite conical-shellshaving their bases opposngleal 'other' and djnstably connected and ,attheir outer ends provided -with longitudinally-disposed teeth, of acentral roller provided at its end-s with teeth corresponding inlengthwith those of the shells and havingan external configuration'opposite to that of the shells, 'and a series of auxiliary rollers lo-5o .W'ithlthose of the shells and provided at its ends withjspur-gearsfor engaging the teeth `of the shells and the teeth of the gears of themain roller, substantially a's specified.

In testimony that I claim the foregoing as 'my own "I haveheretoaixed mysignature in the presence of two witnesses.
